VPT's cuelist is a text script of one-letter commands that sequences presets and parameters

The cuelist is a line-by-line text script driving VPT’s runtime. Core commands: F fades (interpolates) from one preset to another over N seconds, C cuts directly to a preset, D delays N seconds before the next cue, L jumps to a given line (for looping), S activates a source preset, O sends an OSC message internally to any VPT parameter, X sends OSC out to another application, and R ramps a router controller value over time. Appending ’+’ to a line auto-advances to the next cue when it finishes; in play mode cues are stepped manually or chained automatically via ’+’. You can edit cues inline, in the built-in editor (ending the list with ‘end’), or write a cuelist in any text editor and import it.

Examples

F 1 2 3 + / D 5 / C 3 — fades preset 1 to 2 over 3 s, waits 5 s, then cuts to preset 3.

Assessment

Write a cuelist that fades preset 1 to 2 in 4 s, waits 2 s, cuts to preset 3, then loops back to the top. Which command creates the loop, and what does trailing ’+’ do?
